Prevent backspace button navigating to previous page ADF

 

<af:document id="d1" title="#{apptaskflowBundle.AppName_APPLICATION}">

      <af:clientListener method="onloadJSPXPage" type="load"/>

      <af:resource type="javascript" source="javascript/<javascriptfile.js>"/>

Use the method onButtonPressed() on KeyDown event - To disable backspaceon a component like select one choice

On load event of the document call the method onloadJSPXPage() in javascript.js file to avoid navigating to the previous page

*Thanks! to my colleague Gareth Paglinawan for providing the code snippet

function onloadJSPXPage(event) {

    document.onkeydown = function (e) {

        var evt = e ? e : window.event;

        var keyCode = evt.keyCode;

        var tag = evt.srcElement.tagName;

       

        

        if (keyCode == 8){

          if (tag == 'INPUT'){

            return true

          }else{

            return false;

          }

        }

        else{

            return true;

        }

    };

//document.onkeydown = onButtonPressed;//or however you are calling your method

function onButtonPressed(event) {

    var keycode = event.getKeyCode();

    //alert(keycode);

    switch (keycode) {

        case 8:

            event.cancel();

            break;

        case 46:

            break;

        default :

            break;

    }

}
